   Date of Resolved Release: 21-Aug-2008

   SA Document Body
   Sun Fire 12K/15K/E20K/E25K systems equipped with UltraSPARC IV or 
   UltraSPARC IV + System Boards may panic:

   Impact

   Sun Fire 12K/15K/E20K/E25K systems equipped with UltraSPARC IV
   or UltraSPARC IV+ System Boards that use high traffic across a Quad
   GigaSwift (QGE-X) card may panic.
   Contributing Factors

   This issue can occur on the following platforms:
     * Sun Fire 12K/15K/E20K/25K without patch 118777-13

   The described issue only occurs under the following conditions:

   1. The Sun Fire 12K/15K/E20K/E25K is equipped with an UltraSPARC IV or
   UltraSPARC IV+ System Board, and the Quad GigaSwift Ethernet PCIX Card
   (X4445 - 501-6738)

   2. One of the network ports is at or near its peak bandwidth.

   3. The network card is running at a frequency over 66MHz.

   Note: The more CPU's in a domain, the more likely the panic may occur
   while the network port is at its peak bandwidth. This issue has not
   been seen on systems equipped with the UltraSPARC III system boards.

   To determine if a system is equipped with a Quad GigaSwift Ethernet
   PCIX Card (X4445 - 501-6738), the following command can be used:
    # prtdiag
    System Configuration:  Sun Microsystems Sun Fire 25000
    System clock frequency: 150 MHz
    Memory size: 327680 Megabytes
   ...
   /IO01/C3V0  PCI   60   A    90   90  1,0  ok    pci-pci8086,537c.7/network (netw+ pci-bridge
   /IO01/C3V0  PCI   60   A    90   90  0,0  ok    network-pci100b,35.30   SUNW,pci-x-qge
   /IO01/C3V0  PCI   60   A    90   90  1,0  ok    network-pci100b,35.30   SUNW,pci-x-qge
   /IO01/C3V0  PCI   60   A    90   90  2,0  ok    network-pci100b,35.30   SUNW,pci-x-qge
   /IO01/C3V0  PCI   60   A    90   90  3,0  ok    network-pci100b,35.30   SUNW,pci-x-qge
   ...

    Symptoms

   If the described issue occurs, a panic string of "Fatal PCI bus
   error(s)" will be seen.
   Workaround

   To work around the described issue, slow down the QGE-X card to use
   PCI speeds instead of PCIX. This is done by adding a post directive to
   the "postrc" file on the system controller. The "postrc" file is
   different for each domain. If there is not a "postrc" file for a
   specific domain, the platform "postrc" file is used. The domain
   "postrc" files are located at:
    /etc/opt/SUNWSMS/config/A/.postrc
    /etc/opt/SUNWSMS/config/B/.postrc
   /etc/opt/SUNWSMS/config/C/.postrc
    ...
    /etc/opt/SUNWSMS/config/R/.postrc

   The platform "postrc" file is located at:
    /etc/opt/SUNWSMS/config/platform/.postrc

   The postrc directive is a single line that is added to this file. The
   syntax is:
    iobrd_no_pcix      exp [ lport [ bus ]]
    iobrd_no_pcix 1 0 0 # changes IOBoard Slot 0 on IO1.

   Use this "postrc" directive for every QGE-X card that is in the
   platform.

   Below is an example of the postrc directive and its syntax for each
   slot:
    iobrd_no_pcix 3 0 0 # changes IOBoard Slot 0 on IO3.
    iobrd_no_pcix 3 1 0 # changes IOBoard Slot 2 on IO3.
    iobrd_no_pcix 3 1 1 # changes IOBoard Slot 3 on IO3.

   Note: Slot 1 is not a PCIX slot and is not impacted by this issue.
   Resolution

   This issue is adressed in the following release:
     * Sun Fire 12K/15K/E20K/E25K with patch 118777-13 or later
